PU Foaming System

The PU foaming system is mainly comprised of following configurations:
1. Storing, conveying and pre-mixing device
2. High-pressure foaming unit
3. Electrical control cabinet and process control unit
4. Cooling device
5. Spraying device

Storing, Conveying and Pre-mixing Device
This device adopted by the PU foaming machine is incorporated by configurations as below:
1. Two 500L pressure vessels with jacket layer, used for isocyanate and polyol storage
2. One electric stirrer for stirring polyol
3. One electric stirrer for stirring isocyanate
4. Flow transducer and operation panel
5. Conduit coupling

High-pressure Foaming Unit
The high-pressure foaming unit of our PU foaming system is equipped with:
1. Flow transducer and operation panel
2. High-pressure foam machine and spraying head (2 sets)

Electric Control Cabinet and Process Control Unit
1. Power system for high-pressure foaming, PLC
2. Display screen for data supervision and display
3. Working voltage: 380V, 50Hz
4. Boosting voltage: 24V
5. Total power: 70KW
6. Working pressure: 6/8 bar
7. Air consumption: 300NL/min.

Cooling Device
As an accessory device of our PU foaming system, the cooling device forms a closed loop to automatically regulate working temperature of equipment used for mixing polyol and isocyanate.

Spraying Unit
High-pressure rubber hose conveys liquid raw materials to mixing head, and after mixing, the materials are sprayed onto steel sheet in motion. The entire foaming system is controlled by a closed loop and supervised by PLC.

The technical parameters of our PU foam equipment are as below:
1. Moving speed of mixing head: 80m/min.
2. Maximum width for transverse movement: 1500mm
3. Maximum width for longitudinal movement: 1300mm
4. Spraying distance of mixing head: 500mm
5. Adjustment range of mixing head height: 150mm
6. Installed power: 2KW
